It's very light on the skids at engine idle right now, but that's probably due to propeller thrust modeling still being a little buggy and overpowered. It should settle down (for all helicopters) once Austin fixes that.

How did you get this to work? I downloaded the Bell 429 from the link above. I also downloaded the patch. The confusing thing is the patch is a Bell412.acf. I tried renaming it to 429 and putting it in the Bell 429 folder. I also read somewhere that you needed to delete the geforce plugin. I get an error and CTD when I try to load the 429 in XP11pb6.

Unzip and install the 429 files (do it again since you renamed the original .acf file). The only files you need in that Bell 412 patch download are the ones in this folder, not the Bell 412 .acf file:

/plugins/Bell412/64/

lin.xpl

mac.xpl

win.xpl

I know it's a little confusing, but what's happening here is we're installing a patch originally made for the X-Trident Bell 412 to temporarily work while XP11 is in beta. And because the 429 author was allowed to use the original 412 plugin in this helicopter, the same patch works. And it's all in those .xpl files, as far as I know.

I got the AP working (SCAS button to the left of the right most display unit). Press it to ATT and the computer takes over, it will basically do anything. However I don't see a way to disable the SPD hold. I can go back to SCAS mode and all my flight controls work except the "auto throttle" is still engaged. Anyone know of a button or way to turn it off.

If it works like the Bell 412 (and it should, using the same plugin), you can disable AP by assigning a controller or keyboard command to "Servos toggle" or "Servos off" as a generic X-Plane command. It should also work by turning AP1 and AP2 off (or just one, I'm not sure).

Take a look at the commands in the /Documents/Commands.txt folder underneath the main aircraft folder. That has a list of all the special Bell 412 plugin commands for autopilot. You have to map these plugin commands to a controller switch unless you want to just mouse the switches in the cockpit.

Flying helos in XP would definitely be better with actual helo hardware. Especially for online flight there's no good way to change frequencies with a teeny weeny clickspot and hand fly. I see the "beep trim" commands- is that like for force trim? OR is there a way to activate force trim to hold a stick attitude?

Beep trim is for small adjustments in ATT mode (not SAS), where joystick input is limited. In that mode on the X-Trident 412, you can activate force trim release (hold down a button) to hand-fly any changes and then release the button to limit cyclic input again. Beep trim is basically another way to make small cyclic inputs in that mode.

I haven't looked to see if force trim release is actually modeled in this 429, but if it's using the 412 plugin then it might be there. The command you can map for that with the 412 plugin is listed under:

---SPECIAL

---buttons

cyclic force trim release

Alright I'll try. I'm still having a heck of a time with the AP logic. VS mode doesn't seem to capture altitude, even though there is an ALTS on the RDU. I'd like to get it figured out so I can fly it online (AP is great for longer flights and for tuning radios/avionics). Hope the developer makes a manual some day.

Make sure you're in ATT mode with both AP1 and AP2 active for altitude capture. A manual would be nice, but a lot of this stuff is actually the borrowed Bell 412 functions. There is a manual for that one, with more info on the autopilot functions, but I'm not sure it's legit to post it since it's part of the payware X-Trident 412 package. You could always buy the 412 and get that manual. :smile: It's a really good helicopter model.
